2. Air-blast injection - Wikipedia

   en.wikipedia.org/wiki/Air-blast_injection

   Unlike modern designs, air-blast injected Diesel engines do not have an injection pump. A simple low-pressure fuel-feed-pump is used instead to supply the injection nozzle with fuel. At injection, a blast of compressed air presses the fuel into the combustion chamber, hence the name air-blast injection. The compressed air comes from compressed ...

3. Electronically controlled unit injector - Wikipedia

   en.wikipedia.org/wiki/Electronically_controlled...

   As the pump plunger retracts, fuel is drawn into the pump chamber from the fuel supply line. Spill phase The pump plunger begins descending, but the spill valve is open, and fuel recirculates back to the return line. Injection phase Partway through the pump stroke, the solenoid is energized, which closes the spill valve.

4. Unit injector - Wikipedia

   en.wikipedia.org/wiki/Unit_injector

   Early Lucas electronic diesel unit injector. A unit injector (UI) is a high-pressure integrated direct fuel injection system for diesel engines, combining the injector nozzle and the injection pump in a single component.

5. Unit pump - Wikipedia

   en.wikipedia.org/wiki/Unit_pump

   The Unit Pump system [1] is a modular high-pressure diesel injection system, which is closely related to the unit Injector system, and is designed for use in commercial vehicle diesel engines. [ 2 ] The systems use an individual injection pump mounted on the engine block for each cylinder so it is primarily designed for OHV or "cam in the block ...

6. Gasoline pump - Wikipedia

   en.wikipedia.org/wiki/Gasoline_pump

   A gasoline pump or fuel dispenser is a machine at a filling station that is used to pump gasoline (petrol), diesel, or other types of liquid fuel into vehicles. Gasoline pumps are also known as bowsers or petrol bowsers (in Australia and South Africa ), [ 2 ] [ 3 ] petrol pumps (in Commonwealth countries), or gas pumps (in North America ).

7. Common rail - Wikipedia

   en.wikipedia.org/wiki/Common_rail

   Diesel fuel injector as installed in a MAN V8 Diesel engine. Common rail direct fuel injection is a direct fuel injection system built around a high-pressure (over 2,000 bar or 200 MPa or 29,000 psi) fuel rail feeding solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors (or pump nozzles).
